line numbers were off since the patch was made against 1.8 rather than CVS
but it wasn't too hard to apply manually

Sigh, another silly file required by auto*

Obsolete/useless file.

Oops - only want to use the yv12 workaround for 4:2:0, not 4:2:2!

Document the new -U/--use-write option.

see discussion from 24-aug-2006: Re: [Mjpeg-developer] Old mmap->read/write patch into CVS?

libquicktime's yv12 (QUICKTIME_YUV420) codec has the U and V planes reversed.
Basically this causes the data to be in IYUV format but the file has the
fourcc 'yv12'. Discussions on the lqt mailinglist brought out the fact this
is on purpose to maintain compatility with the broken quicktime4linux (from
where the old yv12 codec came).

The default for this program is to put YV12 data into a YV12 file. If brokeness
is desired then use the -k option.

Note: nothing much outside some bt8x8 capture cards support uncompressed 4:2:0
anyhow.

Add 'yv12' (aka I420 4:2:0 etc). libquicktime supports it but Apple's
Quicktime software does not.
